QUICK-ACTION VISE.

SPECIFICATION formingpart of Letters Patent No. 631,151, dated August15, 1899.

Application filed February 10, 1899. Serial No. 705,184. (No model.)

T0 at whom it may concern) Be itknown that I, CYDNOR B. CAMPBELL, acitizen of the United States, residing at Glouster, in the countyofAthens and State of Ohio, have invented new and useful Improvements inQuick-Action Vises, of whichthe following is a specification.

' My invention relates to that class or description of quick-actionvises which comprise in their structure a stationary jaw and a slidableor movable jaw carried by a rackbar and provided with a pivoted dog forholding the sliding jaw in place when an article is clamped between thejaws; and its object is to provide improved means for holdingthe (log inengagement with the rackrbar and'dis engaging it therefrom, so as toenable the rack-bar to be moved in or out.

It is also an object to provide improved means'for securing the vise toits plate or other support whereby it may be swung out of the way oraltogether removed'from said su port when desired.

he invention consists in the novel construction and. combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a viseconstructed in ac cordance with my invention. Fig. 2 is a centrallongitudinal section of the same. Fig. 3 is a similar view showing thepivoted dog in engagement with the rack-bar and held againstdisengagement therefrom by the lug on its front end engaging with arecess in the stationary jaw. Fig. 4 is a plan view of thesupporting-plate, the vise being removed. Fig. 5 is a cross-section onthe line 00 00, Fig. 1. Fig. 6 is a detail sectional view on the line yy, Fig. 2, looking in the direction of the arrows.

In the said drawings the reference-numeral 1 designates a bench or otherobject, to which is secured a supporting-plate 2, seated in a recesstherein. This plate is formed intermediate its ends with a longitudinalslot 3, having a circular opening or hole 5 at the front end somewhatlarger than the slot. The said plate at the front end is formed with arecess 6.

The numeral 7 designates a post, the lower 7 end of which is formed witha head 8, having a peripheral groove 9 therein with which the edges ofthe slot 3 engage and which hold the post in place in the slot.

The numeral 10 designates the stationary jaw connected with said post bytwo horizontal bars 10 with a space therebetween,which bars are providedwith a longitudinal groove 11 in their inner sides, forming a way for arack-bar, hereinafter described. This jaw is provided with a groovedhead 12 similar to head 8, which engages with the recess 6 in the frontend of the plate 2 and prevents the jaw and bars from swinging sidewise.

The numeral 13 designates a sliding rackbar passing through a hole oropening in the stationary jaw and provided on its upper side withrack-teeth 14 and on opposite sides with longitudinal ribs 14", engagingwith the grooves 11. The outer end of this rack-bar is screw-threaded,with which engages a correspondingly-threaded swivel 15. Carried by saidrack-bar and movable thereon is the sliding jaw 16, and interposedbetween this jaw and the swivel is a washer or collar 16. This jaw isformed with a recess through which the rack-bar 13 passes. Pivoted tothe upper end of the post 7 is a rod 17, the front end of which isprovided with a dog 18, havin g teeth 19, adapted to engage with theteeth of the rack-bar. The lower front end of this dog is formed with alug 20, which is adapted to engage with a countersunk recess 21 in thestationary jaw. The said rod at the rear end is provided with anelongated hole, through which the pivot-pin 23 passes, the object ofwhich is to permit the rod to have a limited horizontal movement, sothat the lug 20 can be engaged with and disengaged from the recess 21.At the inner ends the said side bars are formed with approximatelytriangular extensions 24, which form guides for the dog 18. The post 7at its upper end is provided with an anvil 25.

The numeral 26 designates a pin on the under side of the rack-bar tolimit the outward movement of the latter by coming in contact with thestationary jaw.

In practice the swivel is given a turn or two backward, and the movableor sliding dog is moved outward a short distance, and the dog is thrownout of engagement with the rackbar. The latter is now pulled outward adistance sufficient to allow the article to be clamped between the jawsto be inserted in place. The dog is then lowered into engagement withthe rack-bar, and the sliding jaw is then tightened by turning theswivel. This will cause the said sliding jaw to be forced tightlyagainst the article andat the same time the rack-bar to be pulledoutwardly slightly, carrying with it the rod and dog, so the lug 20 ofthe latter will engage with the recess or slot 21 and its disengagementwith the rack-bar be prevented. To remove the article from the jaws, theswivel is turned backward, so as to loosen the sliding jaw, so that itcan be moved forward or outward. The rack-bar can now be moved backward,the teeth of the dog riding over the teeth of the same to adjust thedevice for a differentsized article. At the same time the rod and dogwill be moved backward a sufficient distance for the lug 20 to clear therecess 21. By now raising the dogs out of engagement with the rack-barthe latter can be pulled outwardly to adjust the device for a largerarticle.

To swing the vise out of the way when desired, the post and stationaryjaw are pulled outward, so that the lower end of the latter isdisengaged from the recess in the front of the plate 2. The vise can nowbe swung sidewise, the post serving as a pivot. To remove the vise fromthe plate, it is pulled outward until the head at the lower end of thepost comes into coincidence with the hole at the front end of the slotin the plate, when the adapted to engage with said rack-bar,substantially as described.

2. In a vise, the combination with the post, the horizontal bars securedthereto, the stationary jaw secured to said bars and formed with anopening, the screw-threaded sliding rack-bar, the screw-swivel at thefront of said rack-bar, and the sliding jaw carried by said rack-bar, ofthe rod having an elongated hole in its rear end, the pivot-pin passingtherethrough and through the post, and the dog at the front end of saidrod having teeth in its under side and provided with a lug adapted toengage with a recess in the stationary jaw, substantially as described.

In a vise, the combination with the post, the horizontal bars securedthereto provided with longitudinal grooves in theirinner sides, thestationary jaw secured to said bars and formed with a recessin one side,and an openin g intermediate its ends,and the sliding rackbar formedwith longitudinal ribs, the stoppin secured to said bar, the sliding jawand the screw-swivel, of the rod having an elongated hole in its rearend, the pivot-pin passing therethrough and through the post and the doghaving teeth in its under side and provided with a lug engaging with therecess in the stationary jaw, substantially as described.

4:- The combination with the plate having a horizontal slot therein withan intersecting hole at the front end, and said plate formed with arecess or slot at the front end, of the post having a head at the lowerend formed with a peripheral groove, the stationary jaw having a similarhead adapted to engage with said recess in the front of the plate, thesliding jaw, the rack-bar, and the pivoted rod provided with a dog atthe front end, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
